This site had me baffled. It´s like virtually visiting a city and being able to choose where to go, go into certain shops, see what people were doing. It´s amazing. I never thought that would be possible. So far, there´s only one city , San Francisco, but there will be other american cities soon. Can you imagine once they start doing that with famous capitals in the world, and make it possible to visit famous landmarks without leaving your home? It´s really worth a visit.
